I believe that
	#define x 0
	#include <stdlib.h>
	int main(void) { return x; }
is a strictly conforming program, but it would break if the header uses "x" as
an identifier.

However, I don't agree that this is a mistake in the document.  The prototypes
in the document are merely an anchor for discussing the semantics of the
function; they are not "examples" of how the vendor can legally implement the
header.  Note that prototypes are also supplied for functions that must be
implemented as macros.
